Les Schwab has rubber truck bed liners 4x8 by 3/4" thick. I have some in my dog run. They have a textured grippy side and a slick side... They cost about $40 when I got mine. They are made of recycled tires I believe or at least waste in production of new tires.

I used 5x10 carpet, carpet side up at Keizer Rapids on top of newly poured concrete to protect the pads while they cured for about two weeks and they seemed to have ok traction with the carpet...
